Has anyone ever built a roof with solar panels integrated into the roof (flush mount), a system to catch 100% of the rain that falls on the roof and a solarhot water system that was installed under the solar panels and roof surface?

there are hybrid modules combining solar heat gain with photovoltaic electricity production. They sound nice, beause photovoltaics needs low temperatures to work best. The water used for solar heat gain, provides some cooling. Problem is, unless you have a huge demand for hot water, (Think swimming pool) on a good sunny day your heat storage is already hot and will heat the panels instead of cooling them. You should really run your numbers, to determine how much hybrid and how much pure photovoltaic panels you need, to get your optimum.
